Kind Code:
A1
Abstract:
Provided is a method for producing a composition including: a particulate cycloolefin-based polymer having a small particle size; a resin; and a solvent. The method for producing a composition including a resin (A), a particulate cycloolefin-based polymer (B), and a solvent comprises: a step (1) for dissolving a cycloolefin-based polymer (B) in a first solvent to obtain a cycloolefin-based polymer (B) solution; a step (2) for bringing the cycloolefin-based polymer (B) solution into contact with a second solvent and then distilling off the first solvent to obtain a dispersion liquid including the particulate cycloolefin-based polymer (B); and a step (3) for adding the resin (A) to the dispersion liquid.
